Abstract

A new and distinct Persea americana variety having strong resistance to Phytophthora cinnamomi when used as a rootstock. It is a relatively slow growing rootstock having a heavy yield, appearing to have a high yield/canopy volume ratio. ‘Steddom’ has a small degree of salt tolerance and appears to be an all-around, excellent rootstock with small stature and low vigor, making it desirable for high density or hedge-row avocado plantings.
